Weather : NOT great - can not see many stars

From 23:00 to 23:45 the telescope was below 15 degrees - baseplate warmed to >15K.  A full cycle had been completed at ~16:00 and the He4 and He3 fridges held.

To get Orion we decided not to complete a quick cycle.

00:00 - could start to bias detectors - address card did not work at first but started with a 1 minute power cycle.

Scans 1-5 - tests of scan to set focus offsets
Scan 6 - start scan
Scan 7 CAL 1.2V
Scan 8 blank
Scan 9,10,11,12,13 focus 0530+135
For some reason column 0 had bias set to 1000 - rebiased
Scan 14 - cal again 1.2V
Scan 15 - blank

Scan 145 K & ku off 1:31 on 0.37
Scan 146 L,Q,S,ka,K (not x band) off at 1:22 back on 0.2
Scan 147 all on
     Weather - 7:15am very clear overhead. Fairly cold (-3.74C)

Switch to Ka and attempt to get some supporting data on Arp220 and
perhaps M82. We had some trouble with astrid -- plots not showing
up from peak scans -- did a bunch of them and restarted a couple
of times before things started to work (s.154)

Scans 148-161 - peak and focus
Scans 162-166 Nods on apr220
Scans 167,168 Ka band map
